PhonakSoundGrade A

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.

ResoundSoundGrade B

ReSound OMNIA RIE

The ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently priced at $4,498. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #29 of 36 devices in the Prescription Hearing Aid category. This device shows a mixed performance profile in our testing. Its standout strength is speech clarity in quiet environments, scoring 3.7/5—a solid result that sits 0.42 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users concerned about how their own voice sounds while wearing hearing aids. However, the OMNIA RIE struggles significantly in challenging listening situations. Speech-in-noise performance scored just 1.0/5, falling 0.96 points below the category average—a notable limitation for users who frequently encounter noisy restaurants, gatherings, or other difficult acoustic environments. Feedback handling, while strong in absolute terms at 4.1/5, also trails the category average by 0.61 points. Music streaming delivers mixed results at 2.7/5, essentially matching the category average. The OMNIA RIE offers versatile connectivity with both iPhone and Android streaming, hands-free calling capability, and the flexibility of both rechargeable and disposable battery options. At its premium price point, however, several competitors in the same price range—including the Phonak Sphere Infinio and Oticon Intent—deliver substantially higher overall scores. This device may suit users who prioritize quiet conversation clarity and own-voice comfort over challenging noise performance.
